Flipkart — Order Not Delivered even after a week

I have placed an order on 22/09/2022 from Flipkart, and initially the delivery date was 26/09/2022. The Flipkart's delivery partner Ecom Express picked my order and they haven't delivered it till 26, and then flipkart changed the delivery date to 29, and today is 29 and my order is not yet delivered.

Ecom Express send messages daily morning like my order is out for delivery and at the end of the day they cancel the delivery and say that they will retry again tomorrow

They are doing the same from past 5 days. Please help me regarding this issue
